Background and objective: Vitamin K is a fat-soluble vitamin that plays an important role in the coagulation pathways of living organisms. A popular application of vitamin K has been used to help in the extravascular removal of blood from the skin. The aim of the present study was to test the wound healing effect of vitamin K and some common wound dressing agents available in Erbil city clinical settings such; the moist exposed burn ointment (MEBO) and the Cica silver spray to test their combination with vitamin K injections.

Methods: Six groups of albino rats were used (6 rats in each group). Group M received Mebo ointment, Group Creceived Cica silver spray, Group K received Vitamin K injection, Group MK received Mebo ointment+vitamin K injection.Group CK received Cica silver spray +vitamin K Group, and Group N received no- treatment. The duration of the experiments was as 7, 14, and 21 days post wound surgery.The percentage of wound contraction was measured, and the blood serum was collected to test the level of transforming growth factor β (TGFβ) and platelet-derived growth factor (PDGF).

Results: Data presented in our study showed that the best wound contraction percentage(99%) was obtained by the MK treated rats compared to the control group. Similar results were obtained fromTGFβ and PDGF data in which MK group showed a significant increase in the levels of these growth factors.

Conclusion: The wound healing process is supposed to be due to an increase of TGFβ, PDGF, and enhanced fibroblast proliferation and neovascularization of tissues.
